Sealing of skirt base access hole
Thread Content
The access hole at the tower skirt is not sealed, failing to meet the requirements of emergency management. Does anyone have a solution or pictures for sealing the access holes on the pedestal of tower equipment, along with relevant standards? Please share! ! !
This is indeed a key aspect of safety emergency management; inadequate sealing can hinder the ability to cut off supplies and carry out firefighting in emergency situations. I recently participated in a rectification project, and here are a few points for your reference: Standard references: The main guidelines are GB 50160 \"Code for Fire Protection Design of Petrochemical Enterprises\" and the requirements regarding the sealing of openings in the skirt area as specified in SH/T 3007 \"Design Code for Tank Areas in Petrochemical Storage and Transportation Systems\". It is recommended that you check the latest versions of these two standards directly, as they contain clear regulations regarding the need for fireproof sealing at the inspection holes on the skirt. Sealing solution: Generally, it involves sealing welding combined with fire-resistant sealing materials (such as fireproof putty, rock wool, and a double-layer sealing with steel plates). It is necessary to ensure that the inner and outer surfaces are treated for corrosion protection after sealing, without hindering occasional access by personnel for inspections. The specific approach can be referred to the standard fire sealing detail drawings. Image reference: There are indeed many product images available online; for actual construction, one can search for “fireproof sealing details for inspection holes in the skirt base” or “sealing solutions for openings in tower skirt bases”. Some inspection records from petrochemical projects contain photos that can serve as references. However, it is more advisable to have the design institute prepare detailed drawings for the sealing, so that there is a basis for both construction and inspection. Additionally, please note that different projects may have varying levels of safety inspection requirements; it is best to check with your design or safety professionals to see if there are any additional requirements.
What are the specific provisions regarding emergency management? I haven’t seen any standard regulations on this matter. In some places, to prevent small animals from entering the maintenance access holes, these holes are simply covered with thin steel sheets (which are fixed at the top above the access holes)
It cannot be completely sealed off; using a net for isolation is sufficient
We did this some time ago for your reference.
\"Safety Specifications for Special Operations in Hazardous Chemical Enterprises\" (GB30871-2022) 4.5 Before carrying out any operations, hazardous chemical enterprises shall arrange for the operating units to inspect the work site as well as the equipment, facilities, tools, and other items involved in the operations, ensuring that they meet the following requirements: a) The fire access routes and vehicle passage paths at the work site must remain unobstructed, and any debris that could pose a risk to safety must be removed; b) Facilities such as ladders, railings, platforms, walkways, and covers at the work site must be in good condition and secure, and any temporary facilities used must be safe; c) Pits, wells, ditches, holes, and other areas at the work site that could pose a safety risk must be properly protected, with warning signs placed in place; the electrical power supply to equipment that needs maintenance must be reliably disconnected, with the power switch locked and a safety warning sign attached
